text: Induction brazing of wrought magnesium alloy AZ31B using Al matrix filler metal was investigated.Both the phases of brazing seam and the mechanical properties of brazed joint were studied.The interface structure and formation phase of brazing seam of the brazed joint were investigated by scanning electron microscopy,X-ray diffraction and X-ray electron probe microanalysis.The tensile strength of joint and the microhardness of the formation phases were also tested.The results show that Al matrix filler metal has reacted with the base metal and α-Mg,β-Mg17(Al,Zn)12 phases have been produced in brazing seam.Average tensile strength of the butted joint reached 42MPa and average shear strength of the overlapped joint reached 27MPa.The joint mainly exhibits intergranular fracture mode and the fracture comes from β-Mg17(Al,Zn)12 hard brittle phase.
